Now on the Edit Videos page, there is a checkbox to the left of each video title, labeled "Top?". You can choose as many or as few as you like, press "Choose top videos" at the bottom, and the non-selected videos will not be visible in your video profile until the user presses the "Show all" link. (Like the download queue, there are "select all/none/invert" buttons at the bottom of the Edit Videos page)

An example of how this works can be seen in my profile. I've mostly hidden MEPs that were duplicate information (DDR Project MEP vs solo tracks) and ones that I didn't contribute much to.

Note: As a side effect of this change, you now see MEPs you collaborated on in the "Edit Videos" page. They are there so you can set them as favorites (or not), but the titles aren't linked since you can't edit them.

Works fine for me, though I find the number of videos a person has confusing, I guess. Like for Judgeholden, his profile says he has 27 videos, when you click "Show All" it says he has 33. Is there any way to show that 27 out of 33 videos are being displayed, rather than it just looking like he only has 27 videos?

I'm not going to actually use this feature, but I still approve; it provides a solution for people who're somehow embarrassed by their back catalog without the site actually deleting anything, or those videos falling all the way down the memory hole.
